Abeg who knows the importance of an IT log book in the university.

To record your daily activities.

Addon know about ur university but in uniport wen we did IT, d log book was first accessed by ur school-based supervisor which he uses to question ur industry-based supervisor if what ur writing is correct.
But I must say dat not all school supervisors wud scrutinize u oooh some just come to collect money from students, grade u n den leave.
Lastly in U.P ur log book makes up 30% of d entire score, while ur dressing n ur presentation on defence day makes up d rest.....so my dear it is quite important, just drawvur diagrams very well n arrange ur log book neatly...wish u d best, peace.
